RE: Dell Vostro 1710 batttery not charging?
Upgraded BIOS to A12 and still would only show battery charging for a few seconds.
checked PhoenixBIOS Setup Utilities/ Main/ AC Adapter = "NONE".
In desperation I went to PhoenixBIOS Setup Utilities/
1st I disabled 'quickboot to allow boot testing.
2nd under PhoenixBIOS Setup Utilities/ Exit 1/2 way down the list; "Load default settings" and saved on exit.
Rebooted and F2 to PhoenixBIOS Setup Utilities/ MAIN now shows AC Adapter = "90W".
and my battery shows charging
Also I disabled the Quickboot setting to allow tests 1st, but I see the defaults re-enables Quickboot, so am not sure if that made the difference(?) Good Luck.
